Description
Technical field
The present invention relates to roadbed rock blasting means of defence, be specially a kind of existing railway, highway expansion moat excavation rock blasting with polynary stereo safety means of defence.
Background technology
At present; Along with developing rapidly of China railways, the existing railway reconstruction and extension project is a lot, much increases and on former cutting basis, directly expands the moat excavation when building two wires, three-way, four lines; Must take the controlled blasting excavation in cubic meter of stone highway section; But the security risk of Blasting Excavation is very big, and when complicated as if surrounding enviroment, difficulty of construction will be bigger.When bursting work, general single covering, the framed bent retaining of adopting of traditional safety prevention measure protects scheme, and the cost height is constructed loaded down with trivial details and protection effect is relatively poor.
Summary of the invention
The present invention adopts traditional means of defence to have the problem that construction is loaded down with trivial details, cost is high and protection effect is relatively poor in order to solve existing rock blasting, and a kind of polynary stereo safety means of defence is provided.
The present invention adopts following technical scheme to realize: polynary stereo safety means of defence, adopt following steps: a, landform, landforms and blasting engineering quantity according to blow-up point, and survey out the sectional drawing of blow-up point; B, verify blow-up point soil layer, geology and rock mass situation, confirm to expand moat thickness, slope height and strike; C, each aperture cover a big gun quilt, and big gun is pressed a sand hill by last envelope; D, side slope face be SNS flexible anti protecting wire net initiatively fixedly, and the fixing passive flexible anti protecting wire net of SNS of plain stage of slope; The dorsal part of e, the passive flexible anti protecting wire net of SNS is fixed with steel pipe bamboo raft frame, and steel pipe bamboo raft frame comprises horizontal vertical steel pipe cross-join and vertical buried overcoat of steel pipe, and the dorsal part of overcoat is fixed with diagonal brace, and the front side of overcoat is fixed with the bamboo frame plate.Cover big gun quilt, sand hill through aperture, quick-fried district, side slope face SNS is the flexible anti protecting wire net initiatively, effective link of a plurality of unit protection such as passive flexible anti protecting wire net of side slope pin SNS and steel pipe bamboo raft frame, the protection system of formation associating interaction; More than the blasting harm that produces under the corresponding different explosion environmental condition of polynary associating protection system; On solid space, rationally distribute;, form three-dimensional, protection effect comprehensively, completely and efficiently from top to bottom, easy construction, cost is low and protection effect is better.
Existing railway contact net bar front side is fixed with the underground and I-steel that connect through horizontal angle steel of some embeddings; The front side of I-steel is provided with auxiliary sand hill; The rear side of I-steel is provided with diagonal brace or earth anchor rod, when protecting for existing railway contact net bar, adopts the measure of I-steel wall rigid protection; Thoroughly take precautions against the generation of severe harm, further improved protection effect.
The SNS of plain stage of slope is passive, and the flexible anti protecting wire net replaces with the low bank of earth between fields that sand hill is built, and when the plain stage of slope limited space, the artificial low bank of earth between fields is set, and can gather materials on the spot, and is simple and easy to do.
Reasonable in design of the present invention is reliable; Set up quick-fried " the big gun quilt+sand hill " of distinguishing the surface and cover combination, can effectively prevent punching, slungshot, had distinctive flexility through volume rubber big gun and stand bigger blasting impact; And, cover effectiveness and improve greatly through in the sand hill pressurization; Set up side slope SNS initiatively flexible anti protecting wire net, the passive flexible anti protecting wire net of toe SNS and steel pipe bamboo raft frame; The effect of strengthened flexible protection; Can give full play to the self-stable ability of rock slope through distinctive flexibility, science prevents the Rolling Stone spring, tackles Rolling Stone, prevents slope failure; When the plain stage of slope limited space, the artificial low bank of earth between fields is set, can gather materials on the spot, simple and easy to do.Adopt the rigid protection measure to special object,, thoroughly taken precautions against the generation of severe harm like " I-steel wall " protection that catenary mast adopts; Each unit construction technology for protection is simple, and the speed that performs is fast; Each protective unit promptly respectively is directed against, and interlock has each other improved protection effect greatly again, and all protective materials can repeatedly have enough to meet the need, and economic benefit is outstanding.
